DETROIT (AP) — General Motors Co. is adding 181,000 cars in the U.S. and Canada to a 2014 recall for headlights that can stop working, and it will have to repair thousands more for a second time because the first fix could fail again.

The expansion covers the 2005 Buick LaCrosse and the 2007 Pontiac Grand Prix in the U.S., as well as the 2005 Buick Allure in Canada.

A headlight module may overheat and melt in high temperatures under the hood. That can cause the low-beam headlamps and daytime running lights to fail. Dealers will replace the module with an existing part until a permanent repair is developed and installed. GM said Tuesday it knows of no crashes or injuries from the problem.

The recall expansion came after U.S. safety regulators sent the Detroit company a list of consumer complaints about headlight failures in GM cars.

Vehicles that were repaired under the first recall in November of 2014 will have to be repaired again because the replacement part can fail and cut off the headlights, spokesman Alan Adler said.

The 2014 recall affected 316,357 vehicles from 2006 through 2009 including the LaCrosse, Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender.
